ParamHelpers (version 1.3)

addOptPathEl: Add a new element to an optimization path.

Description

Changes the argument in-place. Note that when adding parameters that have associated tranformations, it is probably best to add the untransformed values to the path. Otherwise you have to switch off the feasibility check, as constraints might now not hold anymore.

Dependent parameters whose requirements are not satisfied must be represented by a scalar NA in the input.

Usage

addOptPathEl(op, x, y, dob = getOptPathLength(op) + 1L,
  eol = as.integer(NA), error.message = NA_character_,
  exec.time = NA_real_, extra = NULL,
  check.feasible = !op$add.transformed.x)

Arguments

op

[OptPath] Optimization path.

x

[list] List of parameter values for a point in input space. Must be in same order as parameters.

y

[numeric] Vector of fitness values. Must be in same order as y.names.

dob

[integer(1)] Date of birth of the new parameters. Default is length of path + 1.

eol

[integer(1)] End of life of point. Default is NA.

error.message

[character(1)] Possible error message that occurred for this parameter values. Default is NA.

exec.time

[numeric(1)] Possible exec time for this evaluation. Default is NA.

extra

[list] Possible list of extra values to store. Must be in same order as in extra.par.set of OptPath. Default is NULL

check.feasible

[logical(1)] Should x be checked with isFeasible? Default is TRUE.

Value

• Nothing.
